Six different machines are being considered for use manufacturing rubber seals. The machines are being compare with respect to tensile strength of the product. A random sampl of four seals from each machine is used to determine whether th mean tensile strength varies from machine to machine. Th following are the tensile-strength measurements in kilograms pe square centimeter x 10-¹: 1 17.5 16.9 15.8 3 4 5 20.3 14.6 17.5 15.7 16.7 19.2 17.8 20.8 16.5 18.6 18.9 18.9 20.5 Perform the analysis of variance at the 0.05 level of significanc and indicate whether the mean tensile strengths differ significant for the six machines. Machine 2 16.4 19.2 17.7 15.4 6 18.3 16.2 17.5 20.1
